seeding-mechanism and `furrow-openers are sustainedby a yfront carrying.wheel, `rear caster wheels, and a jointed .supporting structure `betweensaid'. wheels, which permits thefurrow-openers t0 beraisedand lowered.Inthis'type ofy grain-drill yit has been the practice to raise andllower thefurrow openers and seeding mechanismby means of a' handlerigidly'securedzto the machine in such manner that bodily `lift of thefront member of the-supporting structure was necessary toraise theseed-box Kandf'furrow-openers;` In `such mechanism, considerableexertion upon the .part of the operator,

`The present invention designs primarily to provide in `this typeofdrill, `lever-operated raising and 'lowering mechanism 'for `thefurrow-openers `and seed-box, comprising a lever which is fulcrumed onthe structure, so that an effective leverage will be at.`

tainedtofacilitate the raising andlowering operations.

'Ihe invention further designs to provide a grain-drill embodying.improved features of construction. The invention consists in the severalnovel features `hereinafter set forth, and more particularly pointed outby claims'at theccnclusionhereof. l

port the seed-box 6. This front-frame is tiltably sustained by shaft aand the carrying wheel a, to swing about the wheel-axis and to permitthe rear portion `of the frame to be raised or lowered, tocorrespondingly shift the furrow-openers and other mechanism sustainedbyvthe frame and seed-box.

1A rear frame cZ, comprising a cross-bar d and side bars d?, is`pivotally connected to theftiltable' front-frame, by pivot-bolts` (Z3,which pass through the front ends of the side-bars vvof therear-frameand through the side-bars 0f lthe The rear zportio'n'oftherear-frame Z is sus- `tained` by caster-wheels e, each of which isjournaledxon a suitable arm e', which has its front `end pivotally 'heldin `a bracket d,

secured to kthe Arear-frame d.

1 The front and rearfraines, carried the and caster-wheels e,respecpivoted connection between themconstitute a jointed supportingstructhe front-frame, may be raised and lowered to correspondingly shiftthe furrow-openers and seed-box carried thereby.` The tilting of thisfront-frame is controlled by levermechanism, hereinafter set forth.

The grain-drill shown is of the type coinmonly known as a one-horse1drill, in which there is provided a central furrowopener f, anintermediate opener f at each sidethereof, and an outside furrow-openerf2 at each side-of the frame b. Each of these furrow-openers consists ofa suitable disk l0, usually set at an angle to line of draft to cut a`furrow as it is drawn through the soil. Each Afurrower-opener is'provided witha seed-boot 23, which is suitably secured to itsassociated drag-bar,`as is well underwell understood in the art.

rod` or shaft l2 which extendsl between', 4and is secured in theside-bars b ofthe front frame 6. `Each of the drag-bars f?, for openersf', has its front end secured to a lug on 4 a coupling or sleeve 13,which' ,is-slidably and pivotally mounted: on cross-rod 12, so

mechanism supported by a which extends through a verticalslot 15,

in the coupling, to permit this drag-bar to swing responsively to itspressure device.

The lateral adjustment of furrow-openers is controlled by a hand-lever16 which is provided at its rear with a handle 1 7 which is accessiblydisposed to the operator walking at `the rear of the machine, and ispivotally connected, as at 16,-to an arm on the bell-crank lever 18which is pivoted on coupling'l 14, being pivotally held on a bolt 15,which is secured in coupling 14.

Lever 18 comprises two oppositely extending arms 19 to each of which alink 20 is pivoted, and the outer ends of these links are pivoted as .at21 to the sleeves 13, respectively. Resultantly, lever 18, when shiftedabout its pivot 15, will shift coupling sleeves 13 on the cross-rod 12,inwardly or outwardly, to correspondingly adjust dragbars f3 and thefurrow-openers f carried thereby. The rear portion of lever 16 is heldin a guide-,lug 22 which is secured .to the seed-boot 23 for vtheAcentral `furrowopener f, and has notches 23 in its ylower edge forengaging the guide-lug to lockthe lever in its diiferent positions.

Each of the drag-bars f3 `is yieldingly sustained adjacent its rear by apressureV device, comprising a rod 24 pivoted at its lower end tothedrag-bar, and having its lupper end slidably held in a lug 25 whichis secured to the seed-box and a spring 26 applied to resist the upwardmovement of the drag-bar. A stop pin 27 at the upperend of rod 24 limitsthe downward movement of the drag-bar relatively to the seed-box. Bymeans of these connections these drag-bars and furrow openers will beraised and lowered with the seed-box, andthe rear portion of the frontsupporting frame to which said box is secured.

Each of the furrow-openers f2 is sustained by a drag-bar f5 whichisdisposed outside of the supporting iframe-work` and is connected at itsfront end to a forked coupling 30,

which is connected to swing laterally, to projecting .lugs on one of thebrackets a2. Bracerods 31 extend throughl brackets a2 andcouplings130 topivotally connect them, and are extended-rearwardly to the seed-box,where-` to the rear terminal of said rods are secured. Each of theseed-boots for the outside furrow-openers is connected to the seed-boxby a strap 32, which has its ends pivoted to the seed-boot and seed-box,respectively. Each :drag-bar f5 is controlled laterally by laspring-connection comprising a rod 33r havstalks. i ,v

In operation, when the `furrow-openers are' ing its outer en'dpivoted ina lug 34l on the drag-bar, and having its inner end slidably andpivotally connected to the sleeve 13, and

a coil-spring 35. These connections for the outer furrow-openers f2cause themv to be yieldingly and automatically shifted Vwith theurrow-openers-f. o

The seed-box is provided with a Vseeddelivery mechanism 37 of usualconstruction, whereby the seed will be discharged in regulated quantity,into flexible seed-tubes 36 which conduct .the seed into theseed-boots,which deliver the seed into urrows. Seeddel-ivery mechanism 37 is drivenby a chain 38,y and sprocket 39, which is operatively connected to thefront-wheel a by a suitable clutch 40 and a `lever 41, of usual or anysuitable construction controls the operation of the clutch and thedriving mechanism-for the seed-delivery mechanism.

. In grain-drills of this type, asy heretofore constructed, the handlesfor raising and loweringtheseed-box and furrow-openers, were rigidlyconnected to thel seed-box and resultantly it was necessary fortheoperator to lift the seed-box and' parts vertically movabletherewith, bodily aboutthe ulcrum of the front-frame orwheel-axis, andlin thus adjusting the-furrow-openers from lowered to raised positionsand vice versa, considerable power andinconveniencewas necessary,because suliicient leverage to acilitateshift raising andloweringoperationsare greatly facilitated andrendered easy. .Y Thislevermechanism comprises a lever42 for operating, and disposed at, eachside ofthe machine.A Each 4lever 42 Iis pivoted asat 43 to any arm 44`integrally formed with a segmental rack 45 which isrigidlyv secured tothe seed-.box at 46, and to theside-bars of the front-frame b as at 47.v-Each lever 42 is fulcrumed upon alink 48 by a pivot-bolt `49, and eachlink has its lower end pivoted as at 50, to the rear-frame a? of thejointed supporting structure. Each lever 42 is provided with a lock 51controlled by a fingerlever 52, and adapted to engagey with its rack 45tolock the lever-mechanism in its different positions.. Each link isprovided witha hole 48a which permits, by disconsaid holes, the levers.42.to` be Ladjusted rfor the convenient reach of dierent operators.Levers 42 are cross-connected 4for conjoint operation, by la bar 53;Guards 54 are secured to `the lever-handles 55 to protect the hands ofthe `operator from being struck by lowered into the soil, the openers,seedbox andassociated devices, may be veasily `V raised bydepressingfthe handles 550i le-... vers 42, the locks. 51bei`ng.` rst.released is appliedto these handles, .be operated about theirfulcra 49which will from racks 45.
